Use 1 part bleach to 3 parts water, according to Sherwin-Williams. If you don't want to use bleach but do want something other than water, try vinegar, borax or branded products that you can find at a hardware store or home center, which also kill mold.
'Bleach will kill mold spores growing across a hard surface, but if the mold has extended below the surface, then white vinegar is the best choice,' she says. 'The vinegar will penetrate to kill the mold and mildew at the root, preventing it from regrowing.
Using white vinegar to kill mould
If cleaning with detergent doesn't work, it's possible to remove mould using diluted vinegar and a microfibre cloth. If mould cannot be removed using the vinegar method, cleaning with diluted bleach or a commercial product may be required.
While it is possible to use bleach to kill mold as well, experts agree that vinegar is a much better option. Unlike bleach, vinegar can effectively kill the mold at the root, which means it's less likely to return. Vinegar is also less toxic than bleach, making it a better choice for household use.
While a significant mold infestation is best handled by a professional restoration company, you have a powerful weapon against occasional mold growth in your kitchen cupboard: white vinegar. This humble household staple can kill more than 80% of mold species, including hazardous black mold.
To clean mold, use regular white distilled vinegar, typically sold with 5% acidity. You can also use “cleaning vinegar” with 6% acidity. Both are effective at killing mold.
White vinegar is a powerhouse for cleaning, deodorizing, and disinfecting around the house. It can also kill black mold, a mold that commonly appears when there is water damage. Spray vinegar onto the moldy surface and leave it for an hour. Then wipe the area clean with water and allow the surface to dry.
How Long Does it Take for Vinegar to Kill Mold? Depending on the amount of mold, let the vinegar sit on the mold at least 60 minutes before wiping or scrubbing.
2 Vinegar must have an acetic acid level of 4.0%−4.2% or higher to kill mold or mildew. 3 Distilled white vinegar in the condiment aisle contains around 5% acetic acid and 95% water. Cleaning vinegar contains about 6% acetic acid.
Why vinegar and baking soda: Vinegar is a super powerful tool! It kills around 82% of mold species because it has acetic acid. On the other hand, baking soda is great because it absorbs moisture.
Use a bleach solution of no more than 1 cup (8 ounces) household laundry bleach per 1 gallon of water to kill mold on surfaces.
Homeowners can handle cleaning about 10 square feet (roughly 3 feet by 3 feet) of black mold on their own. If the patch is small enough, a combination of bleach, water, scrubbing, and ventilation should do the trick. Before treating mold on your own, prioritize ventilation and protective gear.
The key to mould prevention is keeping air moisture to a minimum. Dry any condensation that may be gathering on your walls, ceiling to windowsills. Dehumidifiers can also help to remove moisture from the air. Try to keep your bathroom and kitchen door shut tightly and ensure your windows are open whilst cooking.
Without constant moisture, mold will become inactive but they never die unless you get rid of them completely. They can always come back to life in the presence of moisture and multiply rapidly causing serious health problems.
Mold professionals use expensive, professional equipment such as HEPA (High Efficiency Particulate Air) air scrubbers, HEPA vacuums, commercial-strength dehumidifiers, etc. Regular handymen won't have that stuff.
For really tough black mold removal, mix two parts baking soda with one part white vinegar and one part water. Stir the mixture until it becomes a thick paste. Spread your mixture liberally onto the surface and let it dry. Scrub away the black mold and stains, and wipe down with water.
Cleaning Walls
Mix together ½ cup of vinegar and 2 cups of warm water. Put the solution into a spray bottle, and apply a light layer onto the wall (don't oversaturate it). Let the solution soak in for a few minutes, then wipe it off with a soft sponge.
Cleaning Mould with Vinegar
A classic vinegar cleaning recipe is 2 parts baking soda to 1 part of white vinegar. However, do not mix vinegar with bleach: it produces chlorine gas, which is extremely dangerous and potentially fatal.
Mix 2 teaspoons of borax with 1/2 cup white vinegar in a spray bottle. Apply the mixture on mildew and let sit for about 30 minutes. The borax will scour the surface while the white vinegar combats the mildew and mold. Rinse with clean water and allow the area to dry thoroughly.
Also, you risk causing damage to the area beneath the mold when you leave the vinegar to sit on it for too long. So when it comes to removing mold with vinegar, it's best to avoid leaving it overnight and stick with the 30 minutes to 1 hour sitting time.
Natural Ways To Get Rid of Mold and Mildew
Vinegar: Spray undiluted white or apple cider vinegar on the mold and let it sit for an hour. Afterwards, wipe the mold. There is not reason to wash it off, as this will create more moisture.
Separately, both vinegar and baking soda work well for cleaning. Alone, baking soda can dissolve grease and dirt, while distilled white vinegar breaks down minerals without adding any coloring to stain surfaces (as apple cider vinegar might).
The reason why vinegar can kill mold while bleach cannot is because the vinegar has antifungal and antibacterial properties. The acetic acid that is present in vinegar has a decently strong pH of 2.5. Because of this strong pH level, vinegar is able to disrupt and stop the growth of mold, fungi, and other organisms.
A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. Mix a 50/50 solution of ammonia and water. Spray on the surface, wait two to three hours, then rinse.
